The Study conducted by the University of Melbourne and RMIT University in collaboration with Monash Business School, analysed data from the Household, Income and Labour Dynamics in Australia (HILDA) survey (2006-2019) to examine the link between internet access and obesity. New research has found that popular high-speed internet activities, like streaming and online gaming, could be contributing to rising obesity rates in Australia.
The Link Between High-Speed Internet and Rising Obesity Rates in Australia
Obesity, which increases the risk of conditions such as heart disease, high blood pressure, and type 2 diabetesis a growing worry in Australia. In 2022, nearly two-thirds (65.8%) of Australian adults were categorized as overweight or obese. The economic impact is also notable: in 2018, obesity cost the Australian economy $11.8 billion, with estimates predicting it could rise to $87.7 billion by 2032.
Dr. Klaus Ackermann, the study’s senior author, described that high-speed internet access contributes to sedentary behaviour, which is important factor in obesity. The study found that the ease of staying connected online for longer intervals leads to lower physical activity. “Access to high-speed internet lowers the likelihood of individuals meeting the minimum physical activity advices set by the WHO,” said Dr. Ackermann. Sedentary behaviour often leads to lower metabolic rates, which merged with snack consumption during internet use, contributes to weight gain.
The Impact of High-Speed Internet on Obesity: The Need for Public Health Awareness
Furthermore, the use of online services reduces the need for physical errands and social interactions, further reducing opportunities for physical activity. The study revealed that a 1% increase in National Broadband Network adoption was related to a 1.57 kg/m² increase in BMI and a 6.6% rise in obesity prevalence.
Dr. Ackermann highlighted the significance of public health campaigns to raise awareness about the risks of excessive screen time and sedentary behaviour. Encouraging breaks between online activities and promoting short bursts of physical activity could help fight the negative effects of increased internet use on public health.
